R factor = 0.052; wR factor = 0.137; data-to-parameter ratio = 14.3. The asymmetric unit of the title compound, C18H18N2O2, consists of two independent molecules, each of which is located about a center of inversion. The molecules are not planar, showing dihedral angles of 55.84 (9) and 54.10 (8) between the piperazinedione and the aromatic rings. The piperazine N atoms exhibit a planar configuration. The crystal packing is stabilized by intermolecular C—H O hydrogen bonds. Related literature For background to the applications of piperazinedione and it
